IMPROVEMENT IN LUBRICATING COMPOUNDS.

Specification forming part of Letters Patent No. 183,343, dated October17, 1876; applicationfiled March 31, 1876.

To all whom it may concern:

Be it known that I, PETER SWEENEY, of the city, county, and State of NewYork, have invented a new and useful Improvement in Compound forLubricating and other Purposes, which invention is fully set forth inthe following specification.

This invention relates to a compound made of beeswax, boiled oil,graphite, and mercury, to which may also be added gelatine, boleArmenia, with or without paper-pulp, the oil being heated and mixed withthe remaining ingredients, and the mass being finally molded to therequired shape, so that the same can be used with advantage injournal-boxes, or for other purposes; or it may. be used forimpregnating gaskets or other packing-rings-of hemp or other material.

In carrying out my invention, I take paperpulp, boiled oil, bees-wax,graphite, and mercury, in about the following proportion: Paperpulp, onepound; bees-wax, four ounces; boiled oil, two pounds; graphite, onepound; mercury, eight ounces; and, if desired, I also add bole Armenia,two ounces; gelatine, two ounces.

I first heat the oil, and then produce an intimate mixture of thepaper-pulp, bees-Wax, and graphite (with or without bole Armenia andgelatine) by stirring these ingredients to-' gether with the heated oil,and heating the mass for about ten hours to from 250 to 500, and whilethe mixture is still hot I stir in the mercury, and after I haveproduced a homogeneous mass I let the same cool.

My compound can be used with great advantage for impregnating gaskets orpackingrings for steam pistons, cylinders, or other similar purposes, orit can be used as a lining for journal-boxes; and in this last-namedcase I prefer to mold my compound under pressure into sheets of fromthree-eighths to one-half an inch in thickness, which I place edgewiseinto the journal-boxes, said sheets being made to alternate withsupporting-layers of rawhide or other equivalent material.

For light machinery my compound can be used as a lining for the entirejournal-box, being molded to fit into such box in the same manner asbrass or other metallic shells are now used.

I also find that a good compound for lubricating purposes is obtainedwithout the paperpulp.

What I claim as new, and desire to secure by Letters Patent, is-

1. A compound for lubricating purposes, made of graphite, boiled oil,bees-wax, mercury, bole Armenia, and gelatine, said ingredients beingmixed together substantially in the manner and in about the proportionsspecified.

2. A compound for lubricating purposes in which is combined paper-pulp,graphite, boiled oil, bees-Wax, and mercury, mixed togethersubstantially in the manner and for the object specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 16th day of March, 1876.
